Abstract (en)
[origin: ES8207096A1] Aluminum zinc phosphate hydrates or basic aluminum zinc phosphate hydrates are manufactured by reacting 1 mole of aluminum hydrogen phosphate with from 2.4 to 4 moles of zinc oxide, if necessary with the addition of up to 0.4 moles of alkali aluminate or the equivalent quantity of alkali hydroxide. A 50% by weight acidic aluminum hydrogen phosphate solution is preferably used for the reaction which is carried out at an elevated temperature in the range from 30 DEG to 80 DEG C. The aluminum zinc phosphate hydrates produced by the method are useful anti-corrosion pigments for use in paints.
